The file 'Spool Holder With And Without Ball Bearings (mounting Rod <10mm Diameter, F.e. Snapmaker Artisan) 3D Printer Model' is (stl,obj) file type, size is 91.2KB.
As I encountered filament pull-up errors with new spools of filament due friction by the weight and the not optimal hanging position in combination with the feed-through on the side of the enclosure I use spool holders, that center the spools for easier turning of the spool.
The ones I had were not ideal, because they were fitting on my Snapmaker A250, but not on my Artisan because of a too narrow diameter in the center and the thread regularly broke when I changed filament (due over tightening).
So I designed my own one in Tinkercad in two versions with and without ball bearings which can be just slided into the spools for fast swapping on filament change.
They work great on my machine (Rod for the spool Holder has 9,5mm diameter)
The ball bearings have 10 mm inner diameter, 26 mm outer diameter and 8 mm width. I bought them from Amazon: https://amzn.to/3SrvKPN
